Product details
Overview
ES2GAHR3G from Taiwan Semiconductor is a 2 A, 400 V super fast recovery surface-mount rectifier diode in DO-214AC (SMA) package, featuring 35 ns reverse recovery time, 1.30 V max forward voltage at 2 A, and 50 A peak surge current - used in DC-DC converters and snubber circuits for high-efficiency power conversion.
For engineers reviewing the ES2GAHR3G datasheet, ES2GAHR3G pinout, ES2GAHR3G application, or ES2GAHR3G equivalent, key selection criteria include repetitive peak reverse voltage (400 V), thermal resistance (RθJL = 20 °C/W), junction temperature range (–55 to +150 °C), and RoHS/halogen-free compliance for industrial and lighting designs.
Technical Context
This super fast rectifier employs a glass-passivated silicon junction optimized for low forward voltage drop and minimal reverse recovery charge, enabling high-frequency switching in SMPS and inverters. Its DO-214AC package supports automated placement and meets J-STD-020 moisture sensitivity level 1.
The device operates with a maximum junction temperature of 150 °C, thermal resistance from junction-to-lead of 20 °C/W, and exhibits stable reverse leakage (<10 µA at 25 °C, <350 µA at 125 °C) across its rated voltage range - critical for reliability in thermally constrained layouts.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 400 V - maximum repetitive reverse blocking voltage without breakdown |
| IF | 2 A continuous - average forward current rating at TL = 75 °C |
| IFSM | 50 A - non-repetitive surge capability for startup/line-transient protection |
| trr | 35 ns - ultra-fast recovery minimizes switching losses in >100 kHz topologies |
| VF | 1.30 V max at IF = 2 A, TJ = 25 °C - low conduction loss improves system efficiency |
| RθJL | 20 °C/W - enables direct heat transfer to PCB copper, supporting compact thermal design |
| Junction temp | –55 to +150 °C - wide operating range for automotive under-hood and industrial environments |

Equivalent & Alternatives
The following parts are listed as comparable options for similar super fast rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| STTH2R04 | Same 2 A / 400 V rating; trr = 30 ns (slightly faster); VF = 1.35 V max | Higher VF increases conduction loss in high-duty-cycle apps | Preferable where ultra-low trr dominates over forward loss |
| MBR240 | Schottky diode: VF = 0.52 V typ but VRRM = 40 V only - not voltage-compatible | Unsuitable for 400 V blocking; limited to low-voltage DC-DC outputs | Only viable if system redesign allows lower VRRM and prioritizes ultra-low VF |
Compared with STTH2R04 and MBR240, ES2GAHR3G delivers optimal balance of 400 V robustness, 35 ns recovery, and 1.30 V forward drop - making it the preferred choice for fixed-voltage 400 V-class flyback and forward converter outputs without layout or BOM changes.

FAQ
What is the maximum junction temperature rating for ES2GAHR3G?
The ES2GAHR3G has a maximum junction temperature (TJ) rating of +150 °C, with a storage temperature range of –55 to +150 °C. This allows reliable operation in high-ambient environments such as enclosed LED drivers or industrial power modules, provided thermal design maintains junction temperature within this limit using the specified RθJL = 20 °C/W path.
Does ES2GAHR3G meet RoHS and halogen-free requirements?
Yes, ES2GAHR3G is RoHS compliant and halogen-free per IEC 61249-2-21. The molding compound is UL 94V-0 rated, and terminals are matte tin-plated to J-STD-002 standards - confirming suitability for environmentally regulated end products including commercial lighting and industrial controls.
What is the reverse recovery time (trr) of ES2GAHR3G and how is it measured?
The ES2GAHR3G has a maximum reverse recovery time (trr) of 35 ns, measured under conditions of IF = 0.5 A, IR = 1.0 A, and Irr = 0.25 A. This value reflects its super fast switching behavior, critical for minimizing switching losses in high-frequency SMPS designs above 100 kHz.
Is ES2GAHR3G pin-compatible with other devices in the ES2x family?
Yes, all ES2x devices including ES2GAHR3G share identical DO-214AC (SMA) package dimensions, anode/cathode pinout, and mechanical footprint. Voltage variants (ES2AA–ES2JA) differ only in VRRM, VF, and CJ; no PCB layout change is needed when upgrading or downgrading within the family.
